lowing 'is a specification.

The invention relates toa-,improvements in apparatus for Hanging, crimping, doubleseeniing or otherwise shaping s` eet metal blanks, in which apparatus the blanlr is to be Worked in successive steps over the entire edge by the successive tools,

T he principal object of my invention is to provide an apparatus for hanging, crinpinff, double seeming, or otherwise shaping sheet metal blanhs by n'lean'sVV of e plurality of clishs or tool elements arranged to operate successively on the blank. A, second object of the invention is to provide an apparatus capable of acting one plurality of blanks at one time and thereby work great saving in time.

Another object oi' the invention is to proviele an apparatus which is continuous Ain operation during the successive ysteps of Working the blank. l

To these objectsthe invention consists of en apparatus ials or performing the successive, operations, and means. to more thc. blanks to contact with the successive 1tools.

'The following length the nature of one form or embodiment of my invention, and the manner in which l' proceed to apply the saine in the `preduction or an apparatus itor hanging,

Figs. 3, Li, 5, and t5 show on a larger 'scale the steps of one form of the 'operations capable oi' being performed by the appafratus, the views being vertical cross-sections through the blanks, part of the blanks being broken away to reduce the size oi th uros. Fig. shows the position of the lav-.anis as specification of Letters Patent.

they are fed into the apparatus, and Figs. e, E and 6 show the successive operations performed by the shaping tools. Fig. is a plan or top view of the apparatus showing means for holiling the blanks against vertical displacement and for holding the cover to the can. Fig. 8 is ay vertical section through one of the guides showing the holding ln the drawings l have shown an apparatus which is particularly adapted to crimp and tlouble' seein covers on lillecl can bodies,

but it is ericient that the apparatus can also otherwise be used for Hanging canboclies or shaping sheet ine-tal blanks dep'eucling on /the shape or" the die forming the shaping tool. l, therefore, do not limit inyself to an apparatus for performing any givenfstep in this operation of shaping sheet metal blanks is eviclent that various operations may be performed by varying the die face of the shaping tools. rEhe shapes of the various tool elements toperiorm the various operations are well known in the art, anni further description thereof is thought unnecessary.

The various shaping tools are arrange. on the successive disks in the order of their opn eration., and in the apparatus shown in the drawings threeshaping tools are employed, Veach performing one step; the whole operation being completed in three steps. Anynurnber of shaping tools can be employed, however, depending on the number of steps vnecessary to complete the operation, the number of disks depending on the number of shaping tools.

The apparatus is voperation upon a frame or table provided with legs or supports 3 for holding the table at suicient height to allow the driving mechanism to be arranged beneath.

The disks 4, 5, 6 having the. shaping tool dies 7-8-9 formed on their circumerences are mounted Jfor rotation above the table Z. These flisks are pressed on to or are otherto the shafts 12, journalecl in the bearings 13 on the table. These bearings 13 may be made integral with the table'or made separate and attached thereto. Rotary motion niay be applied to the disks in any suitable manner and in the present instance l have shown bevel gears i-l on the dish shafts 12, meshing with similar gears l5 on a counter-shaft lo, journalel preferably ,mounted for p ie 'frame ,Motion is imported to l1 Mshnft 16 by means of :i drive pnliey 'ed to any suitable source of ponle: ryingthe shaping tools per le steps of 'the oper e errenged to rotate in opposite dim that the adjneent 'iz-ees enc-li i 'Five disks movie in the .seine direct the point of nearest npjnoeelia the purpose 'holding the blanks neninst the shaping tools and. for e-:inreying t in to the next tool, I h :we provided. froides of snituble'formnnd ntteened to e il in any desirable manner.
